Description
Die Erfindung betrifft ein Getriebe für ein Kraftfahrzeug, sowie einen Antriebsstrang für ein Kraftfahrzeug mit einem solchen Getriebe. Ein Getriebe bezeichnet hier insbesondere ein mehrgängiges Getriebe, bei dem eine Vielzahl von Gängen, also feste Übersetzungsverhältnisse zwischen der Antriebswelle und der Abtriebswelle des Getriebes, durch Schaltelemente vorzugsweise automatisch schaltbar sind. Bei den Schaltelementen handelt es sich hier beispielsweise um Kupplungen oder Bremsen. Derartige Getriebe finden vor allem in Kraftfahrzeugen Anwendung, um die Drehzahl- und Drehmomentabgabecharakteristik der Antriebseinheit den Fahrwiderständen des Fahrzeugs in geeigneter Weise anzupassen. The invention relates to a transmission for a motor vehicle, as well as a drive train for a motor vehicle with such a transmission. A transmission referred to here in particular a multi-speed transmission in which a plurality of gears, so fixed ratios between the drive shaft and the output shaft of the transmission, are preferably automatically switched by switching elements. The switching elements are, for example, clutches or brakes here. Such transmissions are mainly used in motor vehicles to adapt the speed and torque output characteristics of the drive unit to the driving resistance of the vehicle in a suitable manner.
Das Patent
Bei einem Front-Quer oder Heck-Quer-Antriebsstrang ist auf eine besonders kurze axiale Baulänge des Antriebsstrangs zu achten, sodass der Verbund aus Verbrennungsmotor und Getriebe innerhalb der Fahrzeugstruktur angeordnet werden kann. Wie in
Es ist daher Aufgabe der Erfindung, ein Getriebe mitsamt elektrischer Maschine bereitzustellen, welches sich durch eine kürzere axiale Baulänge auszeichnet. It is therefore an object of the invention to provide a transmission together with electrical machine, which is characterized by a shorter axial length.
Die Aufgabe wird gelöst durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen, der Beschreibung sowie aus den Figuren. The object is solved by the features of
Das Getriebe umfasst eine Schnittstelle zu einer getriebe-externen Antriebseinheit, beispielsweise eine Verbrennungskraftmaschine, eine Antriebswelle, eine koaxial zur Antriebswelle angeordnete Abtriebswelle, ein achsparallel zur Antriebswelle angeordnetes Differentialgetriebe, eine Vorrichtung zur Bildung unterschiedlicher Übersetzungsverhältnisse zwischen der Antriebswelle und der Abtriebswelle, sowie eine elektrische Maschine mit einem drehfesten Stator und einem drehbaren Rotor. The transmission comprises an interface to a transmission-external drive unit, for example an internal combustion engine, a drive shaft, an output shaft arranged coaxially to the drive shaft, a differential gear arranged axially parallel to the drive shaft, a device for forming different gear ratios between the drive shaft and the output shaft, and an electric machine with a non-rotating stator and a rotatable rotor.
Die Abtriebswelle steht über einen Kettentrieb und einem koaxial zum Differentialgetriebe angeordneten Nachschaltradsatz mit dem Differentialgetriebe in ständiger Wirkverbindung. In anderen Worten ist das Drehzahlverhältnis zwischen Abtriebswelle und Differentialgetriebe durch das Übersetzungsverhältnis des Kettentriebs und durch das Übersetzungsverhältnis des Nachschaltradsatzes festgelegt. The output shaft is connected via a chain drive and a coaxial to the differential gear arranged with the differential gear in constant operative connection. In other words, the speed ratio between the output shaft and differential gear is determined by the transmission ratio of the chain drive and by the transmission ratio of the Nachschaltradsatzes.
Die elektrische Maschine ist an jenem axialen Ende des Getriebes angeordnet, an welchem die Schnittstelle zur getriebe-externen Antriebseinheit ausgebildet ist. Die Schnittstelle zur getriebe-externen Antriebseinheit ist zur Übertragung einer Drehbewegung von der getriebe-externen Antriebseinheit an die Antriebswelle des Getriebes ausgebildet, und kann beispielsweise als Flansch oder als Steckverzahnung ausgebildet sein. Die Schnittstelle kann auf der Antriebswelle ausgebildet sein oder auf einer mit der Antriebswelle verbindbaren Anschlusswelle. In dieser ständigen oder schaltbaren Verbindung zwischen der getriebe-externen Antriebseinheit und der Antriebswelle können ein oder mehrere Torsionsschwingungsdämpfer angeordnet sein. The electric machine is arranged at that axial end of the transmission, on which the interface to the transmission-external drive unit is formed. The interface to the transmission-external drive unit is designed to transmit a rotational movement of the gear-external drive unit to the drive shaft of the transmission, and may be formed, for example, as a flange or as a spline. The interface may be formed on the drive shaft or on a connectable with the drive shaft connecting shaft. In this permanent or switchable connection between the transmission-external drive unit and the drive shaft, one or more torsional vibration damper may be arranged.
Der Rotor steht mit der Antriebswelle in ständiger Wirkverbindung. Die ständige Verbindung kann dabei als unmittelbare Verbindung oder als mittelbare Verbindung ausgebildet sein. Bei einer unmittelbaren Anbindung des Rotors an die Antriebswelle ist die elektrische Maschine direkt, drehfest mit der Antriebswelle verbunden. Bei einer Ausbildung als mittelbare Verbindung ist der Rotor über ein festes Übersetzungsverhältnis an die Antriebswelle angebunden, beispielsweise über ein Zugmittelgetriebe, über zumindest einen Stirnradsatz oder über einen zusätzlichen Planetenradsatz. Ein Beispiel für ein Zugmittelgetriebe ist ein Kettentrieb. The rotor is in constant operative connection with the drive shaft. The permanent connection can be designed as a direct connection or as an indirect connection. In an immediate connection of the rotor to the drive shaft, the electric machine is directly, rotatably connected to the drive shaft. In an embodiment as an indirect connection, the rotor is connected to the drive shaft via a fixed transmission ratio, for example via a traction mechanism, via at least one spur gear set or via an additional planetary gear set. An example of a traction mechanism is a chain drive.
Erfindungsgemäß ist der Kettentrieb axial zwischen dem Differentialgetriebe und dem Nachschaltradsatz angeordnet. Alternativ dazu ist der Nachschaltradsatz axial zwischen dem Kettentrieb und dem Differentialgetriebe, und der Kettentrieb axial zwischen der elektrischen Maschine und dem Nachschaltradsatz angeordnet. Durch den erfindungsgemäßen axialen Aufbau kann die elektrische Maschine entweder näher an den gangbildendenden Abschnitt des Getriebes angeordnet, oder mit größerem Durchmesser ausgeführt werden. Dadurch kann der gesamte axiale Aufbau des Getriebes verkürzt werden. According to the invention, the chain drive is arranged axially between the differential gear and the rear-mounted gearset. Alternatively, the Nachschaltradsatz is arranged axially between the chain drive and the differential gear, and the chain drive axially between the electric machine and the Nachschaltradsatz. Due to the axial structure according to the invention, the electric machine can either be arranged closer to the gear-forming section of the transmission, or be designed with a larger diameter. As a result, the entire axial structure of the transmission can be shortened.
Ist der Kettentrieb axial zwischen dem Differentialgetriebe und dem Nachschaltradsatz angeordnet, so ist das Differentialgetriebe vorzugsweise an jenem axialen Ende des Getriebes angeordnet, an dem die Schnittstelle zur getriebe-externen Antriebseinheit ausgebildet ist. Dadurch können die Seitenwellen zwischen dem Differentialgetriebe und Antriebsrädern des Kraftfahrzeugs möglichst lang ausgeführt werden können. Dies reduziert den Beugewinkel der Seitenwellengelenke, und somit deren Belastung im Betrieb. If the chain drive is arranged axially between the differential gear and the rear-mounted gearset, the differential gear is preferably arranged at that axial end of the gearbox on which the interface to the transmission-external drive unit is formed. This allows the side shafts between the differential gear and Drive wheels of the motor vehicle can be performed as long as possible. This reduces the flexion angle of the side shaft joints, and thus their load during operation.
Ist der Kettentrieb axial zwischen dem Differentialgetriebe und dem Nachschaltradsatz angeordnet, so kann der Nachschaltradsatz gemäß einer alternativen Ausführungsform axial zwischen der elektrischen Maschine und dem Kettentrieb angeordnet sein. In anderen Worten ist das Differentialgetriebe nun nicht mehr an jenem axialen Ende des Getriebes angeordnet, an dem die Schnittstelle zur getriebe-externen Antriebseinheit ausgebildet ist, sondern axial versetzt dazu in Richtung hinter dem Kettentrieb. Eine solche Ausgestaltung ermöglicht eine Vergrößerung des Durchmessers der elektrischen Maschine, welche beispielsweise als Scheibenläufer ausgebildet sein kann. Die axiale Breite der elektrischen Maschine kann dadurch reduziert werden. If the chain drive is arranged axially between the differential gear and the rear-mounted gearset, then the rear-mounted gearset can, according to an alternative embodiment, be arranged axially between the electric machine and the chain drive. In other words, the differential gear is no longer arranged at that axial end of the transmission on which the interface to the transmission-external drive unit is formed, but axially offset in the direction behind the chain drive. Such a configuration allows an increase in the diameter of the electric machine, which may be formed, for example, as a pancake. The axial width of the electric machine can thereby be reduced.
Vorzugsweise ist der Nachschaltradsatz als ein Minus-Radsatz ausgebildet, dessen Hohlrad ständig drehfest festgesetzt ist, dessen Sonnenrad mit jenem Kettenrad des Kettentriebs ständig verbunden ist, welches koaxial zum Differentialgetriebe angeordnet ist, und dessen Planetenträger mit dem Differentialgetriebe ständig verbunden ist, beispielsweise mit dessen Korb. Preferably, the Nachschaltradsatz is designed as a minus wheel set, the ring gear is fixed permanently rotatably, the sun gear is continuously connected to that sprocket of the chain drive, which is arranged coaxially to the differential gear, and the planet carrier is permanently connected to the differential gear, for example with the basket ,
Die Vorrichtung zur Bildung der unterschiedlichen Übersetzungsverhältnisse zwischen der Antriebswelle und der Abtriebswelle kann auf verschiedene Weisen ausgebildet sein. Die Vorrichtung kann als Vorgelege-Getriebe ausgebildet sein, bei dem zumindest zwei achsparallel zueinander angeordnete Wellen eine Mehrzahl von Festrädern sowie mittels Schaltelementen zur jeweiligen Welle schaltbare Losräder aufweist. Ebenso kann die Vorrichtung eine Mehrzahl von Planetenradsätzen sowie mehrere Schaltelemente zum selektiven Verbinden, beziehungsweise zum selektiven Festsetzen von Elementen der Planetenradsätze aufweisen. Einzelne oder alle Schaltelemente können als kraftschlüssige oder als formschlüssige Schaltelemente ausgebildet sein. The device for forming the different gear ratios between the drive shaft and the output shaft may be formed in various ways. The device may be formed as a countershaft transmission, in which at least two axially parallel to each other arranged shafts has a plurality of fixed wheels and by means of switching elements to the respective shaft switchable idler gears. Likewise, the device may comprise a plurality of planetary gear sets and a plurality of switching elements for selectively connecting, or for selectively setting elements of the planetary gear sets. Individual or all switching elements can be designed as non-positive or as a form-locking switching elements.
Bei einer Ausbildung der oben bezeichneten Vorrichtung mittels Planetenradsätzen kann zur weiteren Verkürzung der axialen Getriebebaulänge eines der Schaltelemente radial innerhalb jenes Kettenrads angeordnet werden, welches koaxial zur Antriebswelle angeordnet ist. Dabei handelt es sich bevorzugt um ein kraftschlüssiges Schaltelement. In an embodiment of the device described above by means of planetary gear sets can be arranged to further shorten the axial transmission length of one of the switching elements radially within that sprocket, which is arranged coaxially to the drive shaft. This is preferably a frictional switching element.
Vorzugsweise ist die elektrische Maschine koaxial zur Antriebswelle angeordnet. Die elektrische Maschine nimmt dabei etwa jenen Bauraum ein, welcher bei einem herkömmlichen Automatikgetriebe für den Drehmomentwandler vorgesehen ist. Besonders bei hohem Nenn-Drehmoment der elektrischen Maschine kann die axiale Baulänge der elektrischen Maschine die axiale Baulänge eines üblichen Drehmomentwandlers jedoch deutlich überragen. Preferably, the electric machine is arranged coaxially with the drive shaft. The electric machine takes about the space that is provided in a conventional automatic transmission for the torque converter. However, especially at high rated torque of the electric machine, the axial length of the electric machine can significantly exceed the axial length of a conventional torque converter.
Alternativ dazu kann die elektrische Maschine achsparallel zur Antriebswelle angeordnet sein. Die ständige Wirkverbindung zwischen Antriebswelle und Rotor der elektrischen Maschine ist durch ein geeignetes Getriebe zu überbrücken, beispielsweise mittels eines Stirnradsatzes oder mittels eines Kettentriebs. Durch diesen Achsversatz kann der Bauraumkonflikt zwischen elektrischer Maschine, Nachschaltradsatz und Differentialgetriebe leichter aufgelöst werden, da elektrische Maschine und Differentialgetriebe an unterschiedlichen Winkellagen um die Antriebswellenachse herum angeordnet werden können. Jedoch ist der im Kraftfahrzeug zur Verfügung stehende Bauraum durch andere Komponenten begrenzt, sodass der Bauraumkonflikt dennoch auftreten kann. Die eingangs genannten Maßnahmen erhöhen bei einer solchen achsversetzten Anordnung der elektrischen Maschine die Flexibilität der Anordnungen, sodass der Bauraumkonflikt vermieden werden kann. Alternatively, the electric machine may be arranged axially parallel to the drive shaft. The permanent operative connection between the drive shaft and rotor of the electric machine is to be bridged by a suitable gear, for example by means of a spur gear or by means of a chain drive. Through this axial offset, the space conflict between the electric machine, rear-mounted and differential gears can be resolved more easily, since the electric machine and differential can be arranged at different angular positions around the drive shaft axis around. However, the space available in the vehicle space is limited by other components, so that the space conflict can still occur. The measures mentioned above increase the flexibility of the arrangements in such an offset arrangement of the electrical machine, so that the space conflict can be avoided.
Die Erfindung betrifft ebenso einen Hybridantriebsstrang für ein Kraftfahrzeug mit einem zuvor beschriebenen Getriebe. Der Hybridantriebsstrang weist neben dem Getriebe auch eine Verbrennungskraftmaschine auf, welche über zumindest einen Torsionsschwingungsdämpfer mit der Antriebswelle des Getriebes drehelastisch verbunden, bzw. verbindbar ist. Zwischen Antriebswelle und Verbrennungskraftmaschine kann sich eine Trennkupplung befinden, welche Bestandteil des Getriebes sein kann. Ausgangswellen des Differentialgetriebes sind mit Antriebsrädern des Kraftfahrzeugs verbunden. Der Hybridantriebsstrang ermöglicht mehrere Antriebsmodi des Kraftfahrzeugs. In einem elektrischen Fahrbetrieb wird das Kraftfahrzeug von der elektrischen Maschine des Getriebes angetrieben. In einem verbrennungsmotorischen Betrieb wird das Kraftfahrzeug von der Verbrennungskraftmaschine angetrieben. In einem hybridischen Betrieb wird das Kraftfahrzeug sowohl von der Verbrennungskraftmaschine als auch von der elektrischen Maschine des Getriebes angetrieben. The invention also relates to a hybrid powertrain for a motor vehicle with a transmission described above. In addition to the transmission, the hybrid drive train also has an internal combustion engine, which is connected in a torsionally elastic manner to the drive shaft of the transmission via at least one torsional vibration damper. Between drive shaft and internal combustion engine, there may be a separating clutch, which may be part of the transmission. Output shafts of the differential gear are connected to drive wheels of the motor vehicle. The hybrid powertrain allows multiple drive modes of the motor vehicle. In an electric driving operation, the motor vehicle is driven by the electric machine of the transmission. In an internal combustion engine operation, the motor vehicle is driven by the internal combustion engine. In a hybrid operation, the motor vehicle is driven by both the internal combustion engine and the electric machine of the transmission.
Eine ständige Verbindung wird als Verbindung zwischen zwei Elementen bezeichnet, die stets besteht. Derart ständig verbundene Elemente drehen stets mit der gleichen Abhängigkeit zwischen deren Drehzahlen. In einer ständigen Verbindung zwischen zwei Elementen kann sich kein Schaltelement befinden. Eine ständige Verbindung ist daher von einer schaltbaren Verbindung zu unterscheiden. Eine ständig drehfeste Verbindung wird als Verbindung zwischen zwei Elementen bezeichnet, die stets besteht und deren verbundene Elemente somit stets die gleiche Drehzahl aufweisen. A permanent connection is called a connection between two elements that always exists. Such constantly connected elements always rotate with the same dependence between their speeds. In a permanent connection between two elements, no switching element can be located. A permanent connection must therefore be distinguished from a switchable connection. A permanently non-rotatable connection is referred to as a connection between two elements, which always exists and their connected elements thus always have the same speed.

Der Nachschaltradsatz P ist als ein Minus-Radsatz ausgebildet. Ein Minus-Radsatz bezeichnet einen Planetenradsatz mit einem Planetenträger, an dem die Planetenräder drehbar gelagert sind, mit einem Sonnenrad und mit einem Hohlrad, wobei die Verzahnung zumindest eines der Planetenräder sowohl mit der Verzahnung des Sonnenrades, als auch mit der Verzahnung des Hohlrades kämmt, wodurch das Hohlrad und das Sonnenrad in entgegengesetzte Drehrichtungen rotieren, wenn das Sonnenrad bei feststehendem Planetenträger rotiert.

Ein Sonnenrad E1 des Nachschaltradsatzes P ist mit dem Korb des Differentialgetriebes AG ständig verbunden. The Nachschaltradsatz P is designed as a minus wheelset. A minus wheel set denotes a planetary gear set with a planet carrier on which the planetary gears are rotatably mounted, with a sun gear and with a ring gear, wherein the toothing meshes at least one of the planetary gears with both the teeth of the sun gear, and with the teeth of the ring gear, whereby the ring gear and the sun gear rotate in opposite directions of rotation when the sun gear rotates when the planet carrier is stationary. It is shown only one half of the Nachschaltradsatzes P. A ring gear E3 of the Nachschaltradsatzes P is fixed permanently rotatably. A sun gear E1 of the Nachschaltradsatzes P is permanently connected to the basket of the differential gear AG.
